Ever since publicly coming out in a YouTube video in 2013, Troye Sivan has been an important young voice for LGBT people. It’s something he’s carried over into his fledgling music career as well; unlike some other artists, he’s not afraid to write songs with male pronouns or to depict gay relationships in his music videos.

But perhaps most importantly, the 20-year-old singer’s openness about his own sexuality has inspired fans around the world to embrace theirs as well. That was never clearer than during his Blue Neighbourhood Tour stop in Washington D.C. on Monday night, where he helped a girl come out to her mom.

In a video posted to Twitter, Troye is onstage, about to read a note that was given to him by a fan named Kelly. “Are you sure?” he asks, and when she says yes, he reads the message, addressed to her mom, who was also in the crowd that night: “If you’re reading this, can you announce that Kelly is bisexual, please?” The audience then erupts into applause and Troye goes over to Kelly, shakes her hand, and blows her a kiss.

After the show, Kelly shared a video of her and her mom reuniting after the show, and it’s utterly heartwarming. They hug, Kelly cries, and they tell each other how much they love each other.

Kelly also tweeted Troye after the show to thank him — because, even if he was only able to directly help one person, it ended up creating a ripple effect that inspired at least one other fan to come out as well. And that’s definitely something worth celebrating.
